drift voltage การใช้

• Using a drift voltage of 25 kV in a 15 cm long atmospheric pressure drift tube, a resolving power above 250 is achievable even for small, single charged ions.
• A GEM-based detector requires several independent voltage settings : a drift voltage to guide electrons from the ionization point to the GEM, an amplification voltage, and an extraction / transfer voltage to guide electrons from the GEM exit to the readout plane.
